[R] operating on a subset of a dataframe

[Tim Wilson]

Hi everyone,

I've got a dataframe with columns of different types. A certain number
of columns in the dataframe hold the results of a series of Likert-type
items. I've got a function that will print a simple table of frequencies
and I want to apply that function to those columns of the dataframe
only. What's the best approach?

-Tim
